* fix(#3842): stage the emitted-drift-ack sweep around open PRs The guard-no-ack-on-next sweep (#3078) deleted every all-spent fragment under tests/emitted-drift-acks/ unconditionally. When an open PR still modified the same fragment file, that delete became a modify/delete conflict on the PR's next merge attempt -- the exact shared-file conflict fragments were adopted (#2914) to eliminate, reintroduced by the sweep itself. The first real sweep hit three open, outside- contributor PRs simultaneously (#3330, #3774, #3648), each with the swept fragment as its only conflicting path. assertNoAllSpentFragments now accepts an optional openPrTouchedPaths set (or the sentinel 'unknown') and partitions all-spent fragments into "safe to sweep" and "held" -- a held fragment is reported informationally, never as a failure, and is swept once the touching PR merges or closes. fetchOpenPrTouchedAckPaths computes the touched set with a single `gh pr list --json number,files` call. The guard-next codepath is factored out of main() into the exported, dependency- injectable runGuardNext() so this wiring is unit-testable without a real, network-dependent `gh` binary. The new behavior is strictly opt-in via a --defer-to-open-prs flag, wired only from the guard-no-ack-on-next job in test.yml (which also gains pull-requests: read and a GH_TOKEN env for the `gh` call). Every pre-#3842 caller -- including every existing test -- is unaffected when the flag is omitted. CONTRIBUTING.md's "Why fragments, not one file (#2914)" section now documents the staged-sweep policy so it no longer reads as though fragments are unconditionally conflict-free once spent. Refs #3842 Co-Authored-By: Claude Opus 5 <noreply@anthropic.com> * fix(#3842): unify the failed-open-PR-check message to one greppable phrase The remote matrix (commit 4ec4527fb) failed two tests on the fail-closed path: assertNoAllSpentFragments's 'unknown' sentinel branch described the failure as "...could not be determined this run...", while runGuardNext's catch around fetchOpenPrTouchedAckPaths described the same condition as "open-PR check failed (<err>)". Both messages were genuinely present and informative (not missing or empty), but they used different wording for the same fail-closed condition, so there is no single string a human scanning CI output can search for to find out why nothing got swept. Unify both sites on "open-PR check unavailable" -- runGuardNext's line now reads "open-PR check unavailable — <err.message>", and assertNoAllSpentFragments's holdAll message now leads with "deferred (open-PR check unavailable): ...". This is a real fix to the fail-safe path's diagnosability, not a relaxed test assertion: the two now-failing tests already expected this exact phrase, and the fix makes the code say what the tests (correctly) expected instead of loosening them to match arbitrary prior wording. Refs #3842 Co-Authored-By: Claude Opus 5 <noreply@anthropic.com> * chore(#3842): backfill changeset PR number and retype to Fixed pr:0 backfilled to 3847. Retyped Changed -> Fixed: the change repairs broken sweep behaviour rather than adding any, and its contributor-facing documentation lives in CONTRIBUTING.md at the repo root, which lint-docs-required does not count.

GSD Core
Git. Ship. Done.
English · Português · 简体中文 · 日本語 · 한국어
A light-weight meta-prompting, context engineering, and spec-driven development system for Claude Code, OpenCode, Antigravity CLI, Kimi CLI, Kilo, Codex, Copilot, Cursor, Windsurf, and more.
What is GSD Core
GSD Core is a context-engineering and spec-driven development framework that drives AI coding agents (Claude Code, Codex, Antigravity CLI, Kimi CLI, Copilot, Cursor, and more) through a disciplined phase loop. It solves context rot — the quality degradation that accumulates as an AI fills its context window — by running all heavy research, planning, and execution work in fresh-context subagents while keeping your main session lean.
How it works
Each milestone repeats the same five-step loop, one phase at a time:
- Discuss — capture implementation decisions before anything is planned
- Plan — research, decompose, and verify the plan fits a fresh context window
- Execute — run plans in parallel waves; each executor starts with a clean 200k-token context
- Verify — walk through what was built; diagnose and fix before declaring done
- Ship — create the PR, archive the phase, repeat for the next one
Quickstart
npx @opengsd/gsd-core@latest
The installer prompts for your runtime (Claude Code, OpenCode, Antigravity CLI, Kimi CLI, Kilo, Codex, Copilot, Cursor, Windsurf, and more) and whether to install globally or locally. The installer is required for cross-runtime compatibility — do not copy files from agents/ or commands/ directly.
On another runtime or without Node.js? See Install on your runtime.
Once installed, start a new project or onboard an existing repo:
/gsd-new-project # greenfield project
/gsd-onboard # existing codebase

Why it works
Most AI-coding setups fail at scale because context bloat silently degrades output quality, there is no shared memory between sessions, and nothing verifies that code actually works. GSD Core solves all three: heavy work runs in fresh subagents, structured artifacts like STATE.md and CONTEXT.md survive session boundaries, and the verify step walks through what was built and generates fix plans before a phase is declared done. See docs/explanation/context-engineering.md for the full reasoning.
